1. 130°
I don't remember too many specifics from my past math classes, but I always remembered this because that is an upside-down mirror of the 130° angle.
2. 50°
A straight line is 180°, and 180 - 130 = 50.
Supplementary angles
x+20+5x+10=180
6x+30=180
6x=150
x=25
To solve this we need to use this formula:
a(b+c)=ab+ac
5(7+3x)-12=35+15x-12=15x+23
Answer: 32
Step-by-step explanation:
96 divided by 24 is 4
8x4=32
